Aniston tells Oprah she hasn't split with Vaughn

Jennifer Aniston denied reports she has broken up with Vince Vaughn during a taping of The Oprah Winfrey Show on Wednesday.

The former Friends star was appearing on the show to promote Room 10, a short film she co-directed as a project for Glamour magazine.

Audience member Rochelle Alfaro tells American publication People that Aniston insisted she and Vaughn have not split.

Another audience member, Margaret Stent, said the star rolled her eyes when asked about Vaughn and also insisted that she hadn't gotten breast implants, as one tabloid recently reported, explaining that when she gains weight, it goes to her chest.

Aniston's short film is about a nurse who gains perspective on her marital problems while caring for a dying patient.

Stent adds: "(The film) said that relationships aren't luck, they're hard work, and I think that was really meaningful to people.

"Jen got a little teary-eyed when she was talking about it, too. It was personally meaningful to her."
